Automatic detection and correction of misalignment between display devices

Abstract

Aspects of the subject technology relate to aligning display devices. A trajectory path of a pointer between a first point on a first display device and a second point on a second display device is captured. A first direction of a first portion of the trajectory path on the first display device is determined. A second direction of a second portion of the trajectory path on the second display device is determined. An adjustment value to correct a misalignment between the first display device and the second display device is determined based on a difference between the first direction and the second direction.
